Abstract
The present invention provides a locker latch assembly having a bearing located on the part of the latch where the door-mounted portion of the latch contacts the frame-mounted portion of the latch which increases ease of use, effectiveness of latching, and reduces wear caused by friction between the parts.
Description
The application is the application number of submitting on July 9th, 2004 is 10/887571, name is called the U.S. Patent application of " locker latch assembly " part subsequent application.
Background technology
In many cases, locker and other lockable casees are very useful.Locker for example is generally used for school and motor area, thereby the temporary transient storage of the personal effects is provided when people carry out activity, and people do not need these personal effects when carrying out activity.For example, in school, locker allow student's storage corresponding to the books that are fit to course when the needs, and without carrying the books that a whole day needs all day.Otherwise another purposes of locker be allow to allow with work clothes be replaced by training clothes and.
This locker and the employed latch mechanism wide range of other lockable casees are so that can be pinned case securely.But all these latch mechanism have at least one CONTACT WITH FRICTION point between the parts of latch mechanism, at this place, and the part adjacency and the slip that must intersect.This slip produces friction inherently and causes the wearing and tearing of part between part.Not only along with the increase of wearing and tearing, it is difficult more that the mortise lock operation becomes, and final this wearing and tearing cause mortise lock fault and continuous maintenance.Otherwise this fault has a negative impact to the operability of latch mechanism, and finally the use to locker has a negative impact.
Be starved of the exploitation this friction generation effect of sening as an envoy to and minimize and control the Mortice lock assembly of this friction generation effect, and can improve the durability of the Mortice lock assembly on the locker.Utilization has the Mortice lock assembly that reduces to rub, and has reduced wearing and tearing very bigly, and the life-span of latch mechanism is longer, has finally reduced maintenance issues and cost.Yet the Mortice lock assembly of prior art lacks these required features.
For the latch mechanism of locker, it is highly important that to provide a kind of improved Mortice lock assembly, and this Mortice lock assembly need carry out minimum change to the parts of latch mechanism.
Summary of the invention
The purpose of this invention is to provide a kind of minimized mortise lock parts that are used for latch mechanism of friction and wear that make between the interaction parts.
Another object of the present invention provides a kind of mortise lock parts that reduce the too early wearing and tearing on the parts.
Another purpose of the present invention provides a kind of mortise lock parts that can reduce existing locker latch structural modification that mechanism components is done very bigly.
A further object of the present invention provides a kind of latch mechanism, and this latch mechanism is easily mounted in the existing latch mechanism.Another object of the present invention provides a kind of mortise lock parts, and these mortise lock parts can make latch mechanism minimize.
These and other purposes of the present invention realize by a kind of locker latch assembly that has supporting part is provided, friction and use that this Mortice lock assembly minimizes latch mechanism are easier, with reference to manual, claims and accompanying drawing, will understand described other purposes of the present invention by integral body.
